ERNEST FRANK HANSON, OF DORCHESTER, MASSACHUSETTS, ASSIGNOR TO LIBRARY BUREAU, OF MASSACHUSETTS.

BOSTON, MASSACHUSETTS, A CORPORATION OF SPECIFICATION forming part of Letters Patent No. 692,515, dated February 4, 1902.

Application filed March 7,1901. Serial No. 50,170, (N del.)

To aZZ whom it may concern! Be it known that I, ERNEST FRANK HANSON, a citizen of the United States, residing at Dorchester, in the county of Suifolk and State of Massachusetts, have invented a new and useful Improvement in Numbering Attachments for Printing-Presses, of which the following is a specification.

My invention consists of a nun'iber-printing 1o mechanism whereby a succession of printed blanks may be consecutively numbered while being printed with other characters or not, as desired.

My number-printing machine involves the [5 use of a type-disk counter or progressivenumbering device in which the arrangement and mode of progressive advance of the disks may be according to any acceptable plan.,

This number-printing device is mounted upon or in one of the two essential and prime members of the press, which are exemplified by the platens and printing-cylinders in common use, and is actuated in harmonywith the recurrent cycle of movement of the print: ing-press, so that at each printing impact of the number-printer the numberingdisks have advanced one unitand the number printed advances correspondingly in the'series.

In the drawings hereto annexed, wherein 0 I use like letters to denote like parts, an embodiment of my invention is illustrated.

Figure 1 shows in vertical cross-section the cylinders ofa rotary printing-press and the arrangement of my number-printing device 3 5 thereon.

cylinders and number-printing device. Fig. 3 shows in vertical cross-section the details of the numbering mechanism. Fig. 4 shows the same in Vertical longitudinal section; and Fig. 5 shows the numbering devices in crosssection, as in Fig. 1, but in a different position.

Figs. 1 and 2 show in a general way the application of my inventionto a cylinder-press. 5 C and C are the two prime members of the pressin this case the press-cylindersrotating in the direction indicated by the arrows. T is the so-called turtle, which is ordinarily used for the reception of type, secured to the cylinder 0 by screws F. The

'to the press-frame.

Fig. 2 shows in elevation the pressnumber-printing device P is mounted in the turtle T by means of the filling-blocks F. The printing devices are actuated inharmony with the movement of the press by means of a wiper W, of which to is a wiper-roll secured to a short shaft w", which is journaled in the fork of the arm 10 which arm is secured at the proper position on the bar 10 by a setscrew w. The bar 20 is'rigidly secured As the press-cylinder C rotates aftereach printing impact of the numbering-disks the disk-advancing mechanism is actuated by the wiper TV, between which and the number-printing devices there is the relative movement required to produce this effect.

In Figs. 3, 4, and 5 there are shown the details of a number-printing mechanism which embodies my invention or substantial and material parts thereof. The case B is a rec- 7o ta'n'gular box, preferably of metal, either cast solid or made of securely-fastened plates. The frame F fits within the case B Witha slidingfit and is supported on or secured to (or both) the case B by the springs S, which fit within the sockets S of the frame F. These springs are sufficiently-stiff to offer substantial resistance to the printing impact, but yield to the influence of the counter-actuator, presently to be described.

ing cam F, which performs the functions of a disk-advancer, as it is that portion of the counter mechanism by which the progressive advance of the numbering-disks is brought about. Upon the shaft cl, which extends the length of the frame F, the disks D d 61 D are hung. These disks carry the number-types and are provided with the ratchets d and (Z wherewith to be advanced progressively in the usual manner. Upon the outside of the frame-arm F there projects the pivot-pin g, which serves as a pi vot-bearing for the rockerlever G. The lever G has a heel g and a toe v 9 and the pin g is secured to the toe g and 5 projects through the curved slotf which is cut for the purpose in the arm F Mounted on the shaft d on the side of the frame-arm F there is hung the bell-crank lever L. This lever has a forked end Z, which engages with tea p The upright arm 80 F of the frame F is provided with a protrudthe pin 9 and a pawl-shaft end L which actuates the pawl-shaft 7L and the pawls e" F. The pawl z" engages with the teeth of the ratchet-wheel cl and advances the first disk D of the series with each throw of the pawl t". The spring i serves by its torsional effect tohold the pawls in effective position. The lever-arm L, mounted on the disk-shaft d, constitutes a proper support for the farther end of the pawl-shaft t'.

The counter -actnator, consisting of the wiper XV, Figs. 1 and 2, is partially shown in Figs. 3, 4, and 5. The wiper-roll w on its shaft "20 is so mounted in the press that the relative movement of the parts carries the wiper-roll w in a path substantially parallel to the face of the printing-press member, platen, or cylinder or what is the same thing, so that the movement, say, of the cylinder carries the printingcounter in a path which is intersected by the wiper-roll. The movement of the wiper-roll relatively to the print ing-counter is indicated by the arrowsin Figs. 3 and 5. The heel g of the rocker G projects into an opening I), cut for the purpose in the side of the case 13, and stands between the ledges Z) and b as shown in Figs. 3 and 5. The high part of the cam F projects above the top of the case B, but lies below the printing-surface, (the plane of the top row of diski-ypcs,) so that the cam F does not in any way interfere with the act of printing and does not come in contact with the in king-rolls wherever they may be placed or however they may be operated. As the press, with the printing-countersecuredin the face ofoneofthe primemembers of the press, proceeds to print it brings the disk-advancer of the counter into operative relationship with the counter-actuator. In the illustration here given the rotation of the cylinder (3 brings the cam F of the counter Pinto contact with the stationary wiperroll to after each printing im pact. The parts are shown at the moment of contact in Figs. 3 and 4, when the cam F is about to be depressed by the wiper-roll 10. In Fig. 5 the cam F is shown in its position of complete depression. As the wiper-roll 'w presses the cam F down the frame F, of which the cam F is substantially a part, is pushed down in the case B against the stress of the springs S. The heel g of the rocker Gis thus broughtinto contact with the ledge b and the too 9 dethe bell-cran k L and the connected pawl back to the normal position shownin Fig. 3, thereby advancing the counter one unit or numher in preparation for the next printing impact. The counter is so arranged that the printing impact may not disturb the positions of the type-disks. As indicated by the arrows in Figs. 3 and 5, the movement of the counter is such that the tangential component of the printing impact will be exerted against the normal course of advance of the disks and so that the pawls of the counter will resist any tendency to untimely displacement of the type-disks. The same safeguard prevents the inking-rolls from disturbing the disks.

\Vhat I claim, and desire to secure by Letters Patent, is-

1. In a printing-counter, the combination of a case, a disk'frame slidingly mounted in the case, diskadvancing mechanism connected with the frame and actuated by its sliding movement, an actuating cam or projection forming part of and projecting from the frame to a height below that of the printing row of characters on the disks substantially as described.

2. The combination, with one of the prime members of a printing-press of a printingcounter, consisting of a case, a disk-frame slidingly mounted in the case, and having thereon a disk-actuating cam located below the type-surfaces of the disks, and a wiper, mounted on the press-frame and adapted to make contact with the actuating-cam and depress the frame between printing impacts of the counter, substantially as described.
